PHP While循環數組

Question

從數據庫獲得所有結果后，我添加了一些額外的數據（“ Prio”）

我使用$ _POST方法並將以下結果存儲在數組中：

    array (size=4)
  'gereed' => string 'gereed' (length=6)
  1 => 
    array (size=7)
      'prio' => string '1' (length=1)
      'res' => string '456' (length=3)
      'base' => string '190203' (length=6)
      'lot' => string '101' (length=3)
      'split' => string '0' (length=1)
      'sub' => string '0' (length=1)
      'seq' => string '10' (length=2)
  2 => 
    array (size=7)
      'prio' => string '2' (length=1)
      'res' => string '456' (length=3)
      'base' => string '180676' (length=6)
      'lot' => string '10' (length=2)
      'split' => string '0' (length=1)
      'sub' => string '0' (length=1)
      'seq' => string '30' (length=2)
  3 => 
    array (size=7)
      'prio' => string '3' (length=1)
      'res' => string '456' (length=3)
      'base' => string '180676' (length=6)
      'lot' => string '10' (length=2)
      'split' => string '0' (length=1)
      'sub' => string '0' (length=1)
      'seq' => string '60' (length=2)

現在我只有3行，但是可能有10行或更多行。

我希望像while循環一樣顯示這些數據。 這樣循環就可以遍歷行（1、2、3，xx），我可以像echo $row['prio'];那樣顯示它們echo $row['prio'];

也許這是一個簡單的問題，但我仍在學習。

編輯！ 在輸入部分，我獲得Prio值。 我想在右行更新此值。

UPDATE VMSCHRIP_SIM SET OPERATION_PRIORITY = $_POST['prio'] WHERE BASE = $_POST['base'] AND RESOURCE = $_POST['res'] AND blablabla

像那樣的東西

這是我的代碼的一部分。

if ($result > 1) {
        $i = 1;
        $stmt->execute();
        while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
            $TrCode = transactionCodeDirect($Employee, $row["WORKORDER_BASE_ID"], $row["WORKORDER_LOT_ID"], $row["WORKORDER_SPLIT_ID"], $row["WORKORDER_SUB_ID"], $row["SEQUENCE_NO"], $row["RESOURCE_ID"]);                  
            if ($TrCode <> ""){
                $actief = "<p class=text-success>Actief</p>";
            }else{
                $actief = "<p class=text-warning>Klaar om te starten</p>";
            }
            if($row["DESCRIPTION"] == ""){
                $description = strtok(wo_description($row["WORKORDER_BASE_ID"], $row["WORKORDER_LOT_ID"], $row["WORKORDER_SPLIT_ID"]), '(**');
            }else{
                $description = $row["PART_ID"]." : ".$row["DESCRIPTION"];
            }
            if($row["PREV_OP"] == "" and $row["MAT_REMAINING"] == '0'){
                $row["PREV_OP_COMPLETED_QTY"] = $row["CALC_END_QTY"];
            }

Answer 1

可能就像這樣。

foreach($_POST as $value){
    if(is_array($value)){
        foreach($value as $key => $val){
            // first iteration
            echo $key; // prio
            echo $val; // 1

            // in second iteration, `$val` contains '2'
        }   
    }
}

Answer 2

由於具有二維數組，因此可以在PHP中使用foreach函數來遍歷數組。 在下面的代碼中，我使用了嵌套的foreach函數來循環二維數組。

echo "<table><tr>th>Key</th><th>Value</th></tr>"; 
foreach($_POST['your_array'] as $value){
    if(is_array($value)){   
           foreach($value as $key => $val){
                echo "<tr>";
                echo "<td>" . $key . "</td>"; // prio
                echo "<td>" . $val . "</td>"; // 1
                echo "</tr>"
            }   

        }
    }
    echo "</table>";
